Was playing around at home in simulator mode on the Garmin 296 the other day and came across some frequency information on it I dont quite understand.
For some small, non-towered airports, it lists frequencies for approach/departure in adition to the CTAF/unicom. For Columbia (o22 - in California in the foothills of the Sierra Nevada) for instance, it indicates 123.70 and 125.10 for approach/departures to the north and west, respectively (nothing listed for for other directions - not sure why).
Who exactly are you talking to on these frequencies and when would you use them? I have always just comunicated on the CTAF at such airports, and only used other frequencies at the larger towered airports. What gives? Maybe these are frequencies to pick up flight following from? If so, seems lame to list them without providing any clues about who you would be communicating with. Probably some plot by you hot shot IFR guys to make us lowly VFR guys look stupid![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
